Trump refuses to condemn violence at his U.S. presidential rallies

WASHINGTON Republican presidential candidate Donald Trump said that "professional agitators" bore much of the blame for violence at his rallies as video showed a protester being beaten and another apparently being grabbed by Trump's campaign manager.

Nor did he back down from his warning that there would be riots in the streets if the Republican Party denied him the nomination for the November election.

"I don't know what's going to happen, but I will say this, you're going to have a lot of unhappy people," he said.

"I don't want to see riots, I don't want to see problems. But you're talking about millions of people," he said.

Scenes of mayhem have become increasingly common at the billionaire businessman's rallies as he secures his position as the Republican frontrunner despite opposition from many senior party officials. Trump has on occasion said that he would like to punch protesters himself.

Television footage from an Arizona rally on Saturday showed a man punching and kicking a protester as he was led out of the event. Another video appeared to show Lewandowski grabbing a protester by the back of his shirt.

Trump declined to condemn the violence and said it was often provoked by protesters, who briefly blocked a highway leading to an Arizona rally on Saturday.

"These people are very disruptive people. They're not innocent lambs," he said.

He also defended Lewandowski and said a security official had actually grabbed the protester. Lewandowski also manhandled a reporter last week, according to the Washington Post.

"I give him credit for having spirit," he said of Lewandowski.

Republican leaders said Trump needs to more clearly discourage his supporters from engaging in violence.

"All of the candidates for president ought to be discouraging that kind of activity, because people in the audience tend to listen to those who are speaking," Senate Republican Leader Mitch McConnell said on ABC.

Republican National Committee Chairman Reince Priebus said the campaign should let law enforcement police the rallies.

"The sheriff there was in the crowd and the Secret Service is there and that's their job to do it," he said on ABC.

"Condoning violence is not the answer."
